Tiffany Crystal

This material is primarily composed of purple fluorite. The stone's matrix typically includes bertrandite, chalcedony, and opal. The mix of the material varies from specimen to specimen, so no two samples can ever be expected to be the same! Bertrandite is of particular note, as this mineral is a source of beryllium. Utah Tiffany Stone is primarily mined for this beryllium, and only a small amount of rough makes it to lapidary use, increasing its rarity further.
